Signing a PDF Online

I needed to sign a rental document recently, but I was away from home and had no printer or scanner nearby. Doing everything by phone seemed confusing at first, and I did not want to change the layout of the original file. I started looking for a simple way to place my signature directly into the PDF and download the finished version. What do you normally use for this?

The game's unexpected success demonstrated 2048 that intricate mechanics and photorealistic visuals are superfluous in capturing players' interest.
